ABSTRACT:
The invention is a conveyor assembly (10) having a vehicle (12) which moves about a track (18). The track (18) includes rails (20) extending therealong for supplying power and command signals to the vehicle (12). The rails (20) are separated into isolated sections separated by buffers (24) with each section supplying electrical signals. The vehicle (12) includes at least two contacting pads (32, 33) for contacting a rail (20) and conducting the electrical signal on the rail (20) to the vehicle (12). The contracting pads are spaced a distance such that at least one contacting pad (32, 33) is in electrical connection with the rail (20) so that the vehicle (12) continuously receives the electrical signals. The receiver (34) of the vehicle (12) receives the signals from both contacting pads (32, 33) and combines the signals while preventing back feeding to the other contact pad (32, 33).
